WRENCH.

Application filed September 17, 1906. $erial No.

and State of Pennsylvania, have invented a new and Improved Wrench, of which the following is a specification.

My invention relates to certain new and useful improvements in wrenches, and in its a wrench of the sliding jaw type, having a special construction of handle member and fixed jaw shank and an improved type of double threaded operating screw and collar therefor which cooperates with the handle and the sliding jaw.

Primarily, my invention has for its object to provide a very simple and effective construction of wrench of the foregoing type, which can be easily and cheaply manufactured and which will readily and ell'ectively serve its intended purposes.

In its more detailed nature, my invention comprises certain new and useful improvements over the type of wrench disclosed in the patent to J as. N. Byington, granted June r0.17s,40s.

I have produced a wrench in which the screw lies closed against the shank, the collar has no motion up or down on the screw alongside the shank, but is held in one position relative to the shank by projecting (and held adjacent the handle) and in which handle and fixed shank are so connected as to afford a maximum strength and rigidity of parts, and relieving as much as possible the strain on the connecting parts.

l/Vith other objects in view than have been heretofore specified, the invention-also comprises certain other novel construction combination and arrangement of parts, all of which will be first described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Figure 1, is a perspective view of my invention. Fig. 2, is a central, vertical, longitudinal section thereof. section on the line 33 of Fig. 2. Fig. 4, is a similar view on the line ll of Fig. 2. Fig. 5, is a perspective view of the fixed jaw and Specification of Letters Patent.

shank. handle.

Referring now to ings, in which like Fig. 6, is a perspective view of the the accompanying drawletters and numerals of reference, indicate like parts in all of the figures, 1 designates the fixed jaw which may be of any approved type, and from which an integrally formed shank l. projects downwardly. The shank l is made practically the full length of the tool and is provided with rivet receiving apertures .l"l. suitably spaced apart as indicated. At a suitable distance between the head, the fixed jaw l.

and the bottom of the shank 1' the shank 1 is cut away as at 1 to form a rectangular shoulder 1 and a hook like shoulder 1 for purposes presently to be explained.

Upon the shank 1, the sliding jaw 2 is mounted and the jaw 2 may be of any apl proved type or design, but as shown in the drawings, the jaw 2 which is apcrtured at 2 to permit passage of the shank 1 and which is connected through a threaded barrel 2 with a yoke member 2 that has an aperture 2 alining with the aperture 2 and also to permit passage of the shank 1.

The yoke 2 has a threaded portion merging with an internally threaded portion 2 of the barrel 2' to receive the screw 3.

The screw 3 in my invention is of similar construction to that shown in Patent No. 178,408, before referred to, and comprises the oppositely threaded portions 3 and 3 the threaded portion 3 cooperating with the threaded portion 2 of the barrel 2 and oke 2 of the sliding jaw.

The handle member 4:, it will be observed is formed with parallel side members 4fi-l having rivet or screw receiving apertures i to cooperate with a similar aperture 1 in the shank 1. Screws or rivets 5 pass through the apertures 4 and l and serve to secure l the handle 4 on the shank l. The handle 4 also comprises a threaded boss 1 having an internally threaded portion t to cooperate with the threaded portion 3 of the screw 3,

and the handle l has its boss l provided with a shank engaging face 4 whose lower extremity is provided with a hook-like edge 4 to cooperate with the edge 4 of the shank l 1 and lock the shank and handle member LII together, it being understood that the surface of the face 4 projects inwardly from the edge 4 of the handle, a sufficient amount to enable it to engage the shank face of the cut away portion 1.

t its lower portion the members 4 are joined by a front plate 4 as shown, the handle member being shown arranged as to leave an open space 4* at the front, and the side members 4* are grooved on their outer faces as at 4" to lighten the construction thereof.

Upon the screw 3 a collar 6 is loosely held, Which collar has a central aperture 6 of sufficient diameter to permit free passage of the screw 3, and the collar 6 is apertured as at 6 to receive a screw lug 7, as indicated, the lug 7 projecting into the central aperture 6*, as shown. The screw 3 has a longitudinal groove 3 extending about onehalf its length, into which groove the screw lug 7 projects and causes the collar and screw 3 to turn together as one. The collar 6 is prevented from riding up and down on the screw 3 with respect to the shank l by reasonof the shoulder l 'of the shank, the collar 6 projecting into the cut away portion 1 of the shank. The collar 6 may have its outer face serrated if desired. Thus it will be noticed that by arranging the parts as shown and described, the collar 6 will lie adjacent the handle 4 and always will be held in such position, and hence the operator may with the same hand that holds the tool, by grasping the collar 6 with his thumb and first finger adjust the wrench to any desired degree.

y reason of the handle 4, when it is desired to detach the handle from the shank l the screws 5 are removed and by pushing against the shank through the aperture 4 the shank can be readily moved to release he engagement of the handle should 4" with that of the shank 1 and the shank may be withdrawn, it being understood that the sliding jaw and screw and its connections with the handle and the sliding jaw are sufiicient to permit the shank be moved as shown in dotted lines in Fig. 2, to disengage the shank and handle. It will also be noticed that by bringing the screw 3 close up to the shank 1 all danger of bending or injuring the screw and its adjustment is avoided since the shank forms as it were, a guard for the screw.

rom the foregoing taken in connection with the accompanying drawings, it is thought the complete construction, operation and numerous advantages of my invention will be readily understood, by those skilled in the art to which it ap pertains, and I desire to say that many slig it changes in the detailed construction, combination and arrangement the cut away portion 4 in i r l i l l i 1 of p arts may be made without dep artingjirom the spirit of the invention or that of the appended claims.
